Abstract
Aim: To isolate aerobic
bacterial micro flora residing in the upper respiratory tract of
equines used by the pilgrims and tourists in Jammu & Kashmir.
Materials and Methods: 88 apparently healthy equines and 53
equines with respiratory tract diseases were used in this study.
Swab samples were collected from the upper respiratory tract of
equines. Isolation and identification of the bacteria was
conducted under aerobic conditions. Each of the sample processed
yielded at least one type of bacteria species.
Results: A total of 321 bacterial isolates were recovered
from both groups of equines. The majority of the isolates were
Gram positive (84.11%) and the rest were Gram negative (15.88%).
Bacterial isolates identified in order of the magnitude were
Streptococcus equi subsp. zooepidemicus (17.44%), Micrococcus spp.
(9.96%), Corynebacterium spp. (9.65%), Staphylococcus intermedius
(9.65%), Staphylococcus aureus (8.72%), Bacillus spp. (7.16%),
Streptococcus pneumonia (5.60%), Staphylococcus chromogens
(5.60%), Streptococcus equismilis (5.29%), Pseudomonas aeruginosa
(5.29%), Rhodococcus equi (3.73%), Escherichia coli (3.73%),
Klebsiella pneumoniae (3.42%), Proteus vulgaris (3.42%), and
Streptococcus equi subsp. equi (1.24%).
Conclusion: The present study reveals the predominance of
Gram positive bacteria in both healthy and diseased animals.
Bacteria were recovered at a higher rate from diseased equines
than from apparently healthy animals. Streptococcus equi subsp.
zooepidemicus was mainly found to be associated with respiratory
tract infections.
Keywords: bacterial flora, equines, respiratory tract,
